+
+## Sending Data
+
+### Sending HTML Form Datas
+
+```hurl
+POST https://example.net/contact
+[FormParams]
+default: false
+token: {{token}}
+email: john.doe@rookie.org
+number: 33611223344
+```
+
+[Doc](https://hurl.dev/docs/request.html#form-parameters)
+
+### Sending Multipart Form Datas
+
+```hurl
+POST https://example.net/upload
+[MultipartFormData]
+field1: value1
+field2: file,example.txt;
+# On can specify the file content type:
+field3: file,example.zip; application/zip
+```
+
+[Doc](https://hurl.dev/docs/request.html#multipart-form-data)
+
+### Posting a JSON Body
+
+With an inline JSON:
+
+```hurl
+POST https://api.example.net/tests
+{
+    "id": "456",
+    "evaluate": true
+}
+```
+
+[Doc](https://hurl.dev/docs/request.html#json-body)
+
+With a local file:
+
+```hurl
+POST https://api.example.net/tests
+Content-Type: application/json
+file,data.json;
+```
+
+[Doc](https://hurl.dev/docs/request.html#file-body)
+
+### Templating a JSON/XML Body
+
+Using templates with [JSON body](https://hurl.dev/docs/request.html#json-body) or [XML body](https://hurl.dev/docs/request.html#xml-body)
+ is not currently supported in Hurl. Besides, you can use templates in [raw string body](https://hurl.dev/docs/request.html#raw-string-body) 
+ with variables to send a JSON or XML body:
+ 
+~~~hurl
+PUT https://api.example.net/hits
+Content-Type: application/json
+```
+{
+    "key0": "{{a_string}}",
+    "key1": {{a_bool}},
+    "key2": {{a_null}},
+    "key3": {{a_number}}
+}
+```
+~~~
+
+Variables can be initialized via command line:
+
+```bash
+$ hurl --variable key0=apple --variable key1=true --variable key2=null --variable key3=42 test.hurl
+```
+
+Resulting in a PUT request with the following JSON body:
+
+```
+{
+    "key0": "apple",
+    "key1": true,
+    "key2": null,
+    "key3": 42
+}
+```
+
+[Doc](https://hurl.dev/docs/request.html#raw-string-body)
+
